Clinical experience with ultra-picosecond “triple skin rejuvenation” in pigmentary disorders

Objetivos: Objective: To evaluate the efficacy and safety of ultra-picosecond lasers at wavelengths of 1064 nm, 532 nm, and 730 nm in treating pigmentary skin disorders. Introducción: Introduction: By selecting specific laser parameters such as wavelength, pulse width, and energy level, specific chromophores can be accurately targeted, and the most suitable laser device can be employed for treatment. Wavelength selectivity restricts absorption to affect only the targeted chromophore. Laser pulse width should be selected to be less than or equal to the thermal relaxation time of the target chromophore, ensuring thermal damage is confined to the unwanted pigment. Laser energy level selection is based on the desired treatment endpoint. Materiales / método: Methods: This study enrolled over a thousand subjects requiring pigment treatment. At 1-week, 4-week, 8-week, and 12-week follow-ups, efficacy was determined by comparing photographic documentation and skin analyzer readings to assess spot lightening and overall facial skin tone improvement. Patients provided subjective assessments of improvements in facial skin tone, pore size, skin texture/luster, and pigmentation. Adverse reactions during treatment and follow-up were recorded, along with patient satisfaction at the final follow-up visit. Resultados: Results: Patients reported sustained improvements of varying degrees in self-assessed facial skin tone, pore size, skin texture radiance, and pigmentation. No significant adverse reactions were observed during treatment or follow-up. Conclusión: Conclusion: Triple-wavelength ultra-picosecond laser demonstrates clear efficacy in treating pigmentary skin disorders. It is safe, painless, and achieves high patient satisfaction, effectively improving facial skin tone, pigmentation, pores, and other photoaging symptoms.
